摘　　要：固液电蚊香是利用固液态转化技术,将液态杀虫剂SR—生物丙烯菊脂在固控剂作用下,转化为固态储存,在电加热器上加热后又迅速由固念转为液态,并挥发至空间,发挥驱杀蚊虫之效,断电冷却后又转为固态。本文介绍该电蚊香对库蚊、伊蚊和按蚊等6种蚊虫的击倒作用和致死效果以及对现场人群的保护效果,并且和4种电驱蚊片和4种液体蚊香击倒活性进行了比较。The solidified liquid electric mosquito-repellent incense (SLEMRI) is made up of three parts: heating apparatus(PTC), a little aluminium pit (20mm in diam(?)ter)and two-pin plug, Esbiothrin insecticide and a controlled-release formulation are added to the pit. The pit is laid on the PTC. The solidi solidibied lied esbinthrin is transforming into liquid state with evaporation to air twhen the electric circuit is set up on. The liquid esbiothrin is transforming into solíd state when the electric circuit is broken. The little pit aided 16) mg esbiothrin can be used for 7 nights(8-10 hours each night). The present experiments were undertaken to determine the effects of SLEMRI against female adult mosquitoes.Tests were made with the knockdown activity of SLEMRI against mosqui toes in the laboratory and with the prot(?)ctive effect in living rooms. Mean KT_(50) of SLEMRI against female Ae.aegypti, Ae.albopictus, An. dirus, Cx. tritaeniorhynchus. Cx. quinquefasciatus and Cx. pipiens pollens following 20 minutes exposure in a glass cabinet (0.343m^3)were 2.0, 3.2, 2.8, 2.4, 5.0 anb 5.9 minutes, respectivly. The 24-hour mortalities were 100, 81.2, 99.0, 100, 35.3 and 20.3%, respectively, Mean KT_(50) of free-flying mosquitoes (Cx. pipiens pollens) following 7 hours exposure in the 41.2m^3 test room with door and windows closed were 71.6-111.2 minutes. Free-flying mosquitoes were knockdown more rapidly than caged ones. The protection effect of SLEMRI tested live was 91.5%.
